If i was moving away from Germany because of too many drugs, the Netherlands wouldn't be my first choice.
Netherlands has higher taxes than Germany, there's also wealth tax and soon some others. But foreigners can deduct their taxes by 30% the first 5 years (the 30% ruling)
Basically OP can move to these places without visa (excluding UK). https://i.pinimg.com/originals/c6/38/10/c63810cb1a63e6529835...
